Larson LXi 288 2009 vs Larson SEi 180 Fish Series I/O 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson LXi 288 2009 or the Larson SEi 180 Fish Series I/O 2005?

For trailering, the Larson SEi 180 Fish Series I/O 2005 has the edge at 265 lbs dry weight versus 6 225 lbs for the Larson LXi 288 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: How many people can each boat hold?

The Larson LXi 288 2009 is Coast Guard rated for 8 passengers, while the Larson SEi 180 Fish Series I/O 2005 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat is wider, and does it affect trailering?

The Larson LXi 288 2009 measures 108" wide, compared to 93" for the Larson SEi 180 Fish Series I/O 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Larson LXi 288 2009 or the Larson SEi 180 Fish Series I/O 2005?

The Larson SEi 180 Fish Series I/O 2005 has the bigger tank at 23 gallons, versus 1 gallons on the Larson LXi 288 2009. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson LXi 288 2009 and Larson SEi 180 Fish Series I/O 2005 from the same manufacturer?

Yes — both the Larson LXi 288 2009 and the Larson SEi 180 Fish Series I/O 2005 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Larson LXi 288 2009 vs Larson SEi 180 Fish Series I/O 2005 — Same Brand, Different Boat

The Larson LXi 288 2009 vs Larson SEi 180 Fish Series I/O 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

For family outings this is probably the sharpest distinction between the two. The Larson LXi 288 2009 is rated for 8 passengers, while the Larson SEi 180 Fish Series I/O 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 288 2009 could be the deciding factor.

Bottom line: Choose the Larson LXi 288 2009 if your priority is putting more people on the water — it handles 8 passengers and at 29,0 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 Fish Series I/O 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
